Happy to knock off 10% if you buy more than one module. Or make me a decent offer for ther lot. You can control quite a lot of your home with the above and the remote is great. It allow you to control eight devices and a macro function as well.It will also contol x10 devices in conjuction with a transceiver. The CM11A will work with all home automation software I have used it with Homeseer, Mcontrol and LinuxMCE it also has some memory for storing macros.
